Divergence in Zygodontomys (rodentia: Sigmodontinae) and distribution of amazonian savannas.

The Journal of heredity - 1 Jan 2000

Abstract excerpt

Northern South America presents a diverse array of nonforest or savanna-like ecosystems that are patchily distributed. The distribution of these open habitats has been quite dynamic during Quaternary glacial-interglacial cycles; yet, the relevance of climatically driven vicariance events to the diversification of nonforest Amazonian vertebrates remains poorly known. We analyzed karyologic and mitochondrial DNA...
